The oxide-nitride passivation layers protect the diode junction to Power dissipation (derate 250 mW linearly to zero 175 C) provide excellent reliability and stable electrical performance, especially when the diode is housed in a hermetically sealed Typical lead strength 8 grams pull assembly to further protect the junction from moisture. Reverse voltage 100 V Performance is guaranteed only under the conditions listed in the specifications table and is The DSG9500-000 is designed for microstrip or stripline circuits not guaranteed under the full range(s) described by the Absolute Maximum Ratings. Exceeding and for circuits requiring high isolation from a series-mounted any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. diode such as broadband multithrow switches, phase shifters, limiters, attenuators and modulators. CAUTION: A lthough these devices are designed to be robust, ESD (Electrostatic Discharge) can cause permanent damage. Skyworks Green products are RoHS (Restriction NeW Static charges may easily produce potentials of several of Hazardous Substances)-compliant, conform to kilovolts on the human body or equipment, which can the EIA/EICTA/JEITA Joint Industry Guide (JIG) discharge without detection. Industry-standard ESD Level A guidelines, are halogen free according to precautions must be employed at all times. IEC-61249-2-21, and contain <1,000 ppm antimony trioxide in polymeric materials.
